Ethernet Motor Communication Recommendations
•
Recommended Ethernet addressing scheme (see
):
Network.Path.Motor
•
Network addresses are used for network configuration
•
Path 0 addresses are used for Subnet configuration:
x.y.0.m
Where:
m
– Node controllers/Network devices
•
Path p addresses are used for motors on that path:
x.y.p.m
Where:
p
– path
m
– motor
•
Maximum number of QSHT 5700 inverters per Ethernet chain = 50.
•
Factory network design must minimize extra traffic on the physical network that the
transport system is using.
•
Only use linear (chain) or star Ethernet connection topologies (see
through
).
•
When using a linear topology, if any device becomes disconnected, all devices
downstream of that device lose communication.
•
Closed-loop (ring) Ethernet connections must be avoided (industry standard
Ethernet practice) to help prevent network saturation.
•
Only pass transport system communication through the Ethernet chains in the
transport system.
•
Large amounts of traffic can degrade the performance of the transport system.
•
Standard IP UDP communication, low latency.
•
100BASE-TX Fast Ethernet (IEEE 802.3u) compliant.
•
Minimum of Cat 5 cabling is required.
•
Ethernet communication topology is independent of transport system configuration
(Ethernet chaining does not have to follow the physical path layout).
•
The use of Allen-Bradley
®
Stratix
®
Managed Ethernet Switches is recommended to
deliver the required network performance.
•
Ethernet chains can consist of multiple paths (as defined in the transport system layout
drawing).
•
Chains do not need to start at the beginning of a path.
•
If all motors in a path are not part of the same Ethernet chain, all chains the path is a
member of must connect to the same network as the node controller.
